The difference that matters

Two 45 ft fifth-wheel toy haulers with near-equal pins, 3,770 lb on the Fuzion and 3,450 lb on the Brinkley. The Fuzion is the lighter trailer, 17,071 lb dry against 18,900, and has the longer garage at 16 ft against 14 ft, plus a Lippert power ramp door and Titan hydraulic leveling. It also carries a very large 173 gal fresh tank with 104 gal gray and black, sleeps eight and has a 5,500 W Flex Power generator with a 30 gal fuel tank.

The Brinkley Model G 3950 is the off-grid build. It comes with 800 W of solar on a Victron MPPT controller, a 200 Ah self-heating lithium bank and a dual-fuel FlexPower 5500 inverter generator fed from a 60 gal fuel station. It rides a triple axle on 17.5 in 16-ply tires, has a 3,000 lb rated low-pitch ramp, fold-away garage bath walls and a 101 in wide body. It sleeps nine with three slides, and its gray capacity is 156 gal.

Keystone Fuzion 419: Riders with long machines who want a 16 ft garage, a huge fresh tank and hydraulic leveling.
Brinkley Model G 3950: Toy hauler owners who dry camp for days and want solar, lithium and an inverter generator included.
